How we approach electric opening rooflights in Portslade
For Portslade homes and buildings we offer electric opening rooflights: hinged rooflights that open on an electric actuator for fresh air. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for electric opening rooflights include kitchens, bathrooms and bedrooms that need fresh air as well as light.
Jobs in Portslade are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Portslade
- Double or triple glazing
- Manual winder on smaller units
- Frame colour to match your doors
- Smart-home or app control (manufacturer dependent)
- Rain and wind sensor
- Electric opening — no poles or winding
- Rain sensor closes the lid automatically
Things we check at survey
- Opening area may count toward purge ventilation for the room
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
Planning and building rules for Portslade
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Electric opening rooflights in Portslade: questions
Is it secure when open?
An opening rooflight is a vent, not an access hatch, so the gap is small. For security, close it when the house is empty — a rain sensor does not lock the unit.
Can I control it from my phone?
Some ranges link to smart-home hubs or their own app. If that matters, say so at survey and we will specify a compatible model.
What happens if it rains while it is open?
With a rain sensor fitted, the actuator closes the lid automatically when the sensor detects water. Without one, the lid stays where you left it, which is why we recommend the sensor on any unit over a kitchen or bedroom.
Will I need planning permission in Portslade?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
Do I need to be at home for the survey in Portslade?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
